Abstract (en)
[origin: EP2527699A2] The valve (22) has an annular blocking body (30) movably arranged in a longitudinal direction of a valve housing. The body is connected with the housing by a corrugated pipe (32), which is arranged parallel to the direction. The body is pretensioned on a truncated cone shaped valve seat (26) in the direction by resilience of the corrugated pipe. A conducting pipe is provided within the corrugated pipe and forms a part of a fluid channel (38) through the valve. The conducting pipe is connected with the body at an end and displaceably mounted relative to the housing at another end. An independent claim is also included for a nozzle pipe.
